Redshift-Dependent Intrinsic Dispersion in the Quasar UV/X-ray Luminosity Relation

Jiaze Gao, Jianping Hu, Yun Chen +2

Accurate modeling of the intrinsic dispersion in the quasar UV/X-ray luminosity relation is essential for reliable cosmological inference. We investigate its redshift dependence us…

Deep Learning Calibration of the Quasar X-ray/UV Luminosity Relation for Cosmological Applications

Jiaze Gao, Yun Chen, Lixin Xu +2

Quasars can serve as standard candles through an empirical scaling relation between their ultraviolet (UV) and X-ray luminosities. As high-redshift probes, it is critical to test w…
